Matte Film on the Galaxy Z Fold8 Inner Screen: Far Fewer Fingerprints, at a Cost to Picture Quality

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Quick take

Fingerprints on the Galaxy Z Fold8’s big inner screen bother me, so I put a matte, anti-glare film on it: PDA Kobo’s Flexible Shield (curved-surface Matte, reduced-reflection type), a film from a Japanese maker. The film itself is good. Fingerprints are much harder to see, it feels silky to swipe on, and the bubbles and streaks left after installation had almost disappeared two days later. The catch is picture quality: the screen looks slightly washed out, with the fine sparkle that matte films always add. For work, reading and browsing it is a great fit. For films, YouTube and photos, I prefer the screen with nothing extra on it.

What I tested

PDA Kobo Flexible Shield (curved-surface Matte, reduced reflection) for the Galaxy Z Fold8 main screen: about ¥2,700 when I bought it. It is a little more than a typical phone film, but a folding inner screen is a very different job from a regular glass protector

I applied the film myself, checked it straight after, then used the phone for two days
Adding a film to a folding inner screen carries more risk than on a normal phone. I did this at my own risk, and if you try it, check the film’s instructions and Samsung’s guidance first

What I found

Applying it was easier than I expected for a folding screen, and easier than another type I tried before. It does not use water, which keeps the process simple. Clean the screen thoroughly first, because there is a lot of area for dust to get in.
Right after applying it, there were small bubbles and, from some angles, vertical streaks. At that point I thought I might have botched it.
After two days of use, the bubbles and streaks were almost invisible. So if you see a few bubbles right after installing, it may be worth waiting a little before peeling it off to try again.

The biggest win is fingerprints. Compared with the glossy screen, I barely noticed them, and I needed to wipe the screen far less. That matters for email, browsing, AI apps and e-books, where you touch the screen constantly.
The surface has the silky feel typical of matte films, with less drag when swiping.
With a glossy film I tried earlier, the two halves of the screen felt slightly sticky when I opened the phone after closing it. I did not notice that with this matte film, which is more important than it sounds on a phone you fold shut.
The downside is image quality. The screen looks slightly whitish, like a thin veil over a very clear display, and there is the fine sparkle that comes with any film that diffuses light to cut reflections. That is a trait of matte films in general rather than a fault of this one. Text is fine, but photos and high-quality video lose some of the Fold8’s clarity.
The centre crease was more noticeable on dark video and films. On bright screens, websites and e-books, it was not much of an issue.

Who it’s for

This film is a good match if fingerprints on your Fold8 drive you mad, you like a silky screen, you want fewer reflections, and you spend more time reading text than watching video: e-books, email, browsing, PDFs, chat, documents and AI apps. It suits anyone using the Fold8 as a small tablet for work. If you mostly watch YouTube and films, look at photos, dislike the matte sparkle or want the crease as invisible as possible, I would leave the inner screen bare. I watch a lot of video on mine, and making the most of that 7.6-inch screen is a big reason I use a Fold, so I prefer it with nothing extra on it.

The video is in Japanese.

Limitations

I used the film for two days, so I cannot say how it holds up over months of folding. Adding a film to a folding inner screen is done at your own risk. PDA Kobo is a Japanese brand and this film may be hard to find outside Japan. Prices are Japanese prices at the time of recording.
